IMPROVED c ourosmou sou FURNITURE AND OTHE mnrosnsl SPECIFICATION.

TO ALL WHOM IT MAY CONCERN:

Be it known that I, JAY J. WIGGIN, of Cincinnati, in the county of Hamilton, and: State of Ohio, have x invented a new and useful Composition for Furniture and other purposes, to which I apply the appellation, i Egyptian Case-Hardened Marble and I do hereby declare the following to be a full, clear, and exact description 1 C of the same. I

The object of my invention is to provide an artificial substitute for wood, metal, and stone, which shall have I the requisite qualities of hardness, neatness, and durability to adapt it for use in the manufacture of floors, coflins, billiard-table foundations, furniture, and for other analogous purposes." i

My invention is carried out in the following manner I take ail aggregation of, say, two parts of sand, one 1 part of air-slaked lime, and one part of ,clay, and boil the whole in coal tar or pitch for about eight hours. At. a heat of about 250 Fahrenheit the liqnid'mass will have the consistency of thin molasses. After thus boiling l the compound, I allow it to cool, when solidification and indnration ensues. The composition when in its liquid state maybe poured-into moulds and made to assume the form of slabs, orit may be otherwise shaped to suit the pure 1 pose to which it is to be applied. It maybe treated or worked up after solidification. It is designed to compose a I foundation for billiard tables. It is also a good material for making coflins and articles of furniture, in the a manufacture of which latter it is intended for general application. I do not restrict myself to the above uses,

as it may, with obvious exceptions, be employed wherever wood or stone is applicable.

Having thus described my invention, the following is what I claim as my invention, and desire to secure by Letters Patent The compound produced by boiling a mixture of sand, lime, and-clay in coal tar or pitch, in the manner and for the purpose substantially as specified.

- J. J. WIGGIN.
